First find the debris field.
Then work your way back to begin scanning the ocean floor.
It'll take time and surface ships.
Nukes have other duties than looking for downed aircraft

The debris will have floated for about 100 miles riding the currents. No
help from that.


As it happens you do get some help from that. The winds and currents can
be used to estimate the position of the crash. That technique was used
to find the remains of Air France 447. They combed the likely area using
a towed sidescan sonor until they found the submerged debris field.
